One of the greatest fighter pilots of WWII was Dublin born, Brendan "Paddy" Finucane. A Wing Commander at the tender age of 21. Crashed into the Channel, was knocked unconscious and drowned whilst returning from a sortie over France.
His dog would always wait at the side of the runway for Paddy's return. When he failed to return, his dog stayed by the runway, refused all food and drink and died of starvation some 10 days later. That's real love and devotion.
